regex help!

anek77713 has asked for the wisdom of the Perl Monks concerning the following question:

sub process_chapter
{
    my ($path, $sections_href) = @_;
    my $text                 = read_file( $path );

    $text =~ s/^L<(\w+)>/insert_section( $sections_href, $1, $path )/e
+mg;

    $text =~ s/(=head1 .*)\n\n=head2 \*{3}/$1/g;
    return $text;
}

what exactly does this regex? $text =~ s/(=head1 .*)\n\n=head2 \*{3}/$1/g;

what exactly does this regex? I don't know, what happened when you tried to run it? What input do you want to run it on? How do I post a question effectively? Without sample data, I could tell you what the punctuation means, but so can perlre. If I had to guess, though, I'd wager it's someone's attempt at reinventing Pod::Parser / Pod::Simple.	[reply]
